I installed everything like it is described in the hacking file.
So I have libtool installed.
I installed it in ~/tools/installed, added .../installed/lib to LD_LIBRARY_PATH
and .../installed/bin to PATH
and after 'autogen.pl' i added '--with-libltdl=/home/georg/tools/installed' to
configure.
See
../configure --prefix=/home/georg/ompi-svn/build-debug
--with-platform=optimized --enable-mpi-java
--with-libltdl=/home/georg/tools/installed --with-jdk-dir=/opt/jdk1.7.0_09
--enable-debug
Now I tried it many times, but since the first installation i have this fault.
I think the problem is in mpi_MPI.c.
#if OPAL_HAVE_LTDL_ADVISE
/* open the library into the global namespace */
if (lt_dladvise_init(&advise)) {
opal_output(0, "LT_DLADVISE INIT FAILED - CANNOT LOAD LIBOMPI");
return JNI_FALSE;
}
if (lt_dladvise_ext(&advise)) {
opal_output(0, "LT_DLADVISE EXT FAILED - CANNOT LOAD LIBOMPI");
lt_dladvise_destroy(&advise);
return JNI_FALSE;
}
if (lt_dladvise_global(&advise)) {
opal_output(0, "LT_DLADVISE GLOBAL FAILED - CANNOT LOAD LIBOMPI");
lt_dladvise_destroy(&advise);
return JNI_FALSE;
}
/* we don't care about the return value
* on dlopen - it might return an error
* because the lib is already loaded,
* depending on the way we were built
*/
lt_dlopenadvise("libmpi", advise);
lt_dladvise_destroy(&advise);
return JNI_TRUE;
#endif
opal_output(0, "NO LT_DLADVISE - CANNOT LOAD LIBOMPI");
/* need to balance the ltdl inits */
lt_dlexit();
/* if we don't have advise, then we are hosed */
return JNI_FALSE;
I looked in the config.log and there stand:
#define OPAL_HAVE_LTDL_ADVISE 0
I think this meens no advice?
So how can I activate advise?
In the configure --help is only the --enable-dlopen option.
But it should be enabled by default.

Betreff: Re: [OMPI users] Java bindings failed to load required libraries
The "libompi" was just a shorthand way of saying it can't load the OMPI
libraries - it actually is looking for the libopen-rte in your /lib directory.
But that isn't the problem. The problem is that we require ltdladvise in order
to correctly load those libraries. Given that you are building from an svn
checkout, we require that this be installed on your machine. Ubuntu does not
install this by default, so you have to do it yourself.
You can do this in two ways:
1. you could look for a libtool package and install it. For example, yum shows
it has "libtool-ltdl" that you could load
2. you could go to the gnu site and download libtool yourself, build it, and
then ensure it is in your default path
Either way will work.
